Big Data Sales Jobs

I have several raw datasets from different business systems that need to be turned into a single, reliable source of truth before we explore the story hidden inside. For the cleaning phase I’ll rely on both Python (think pandas, NumPy, Jupyter notebooks) and advanced Excel techniques such as Power Query and dynamic arrays—whichever makes the job faster and more transparent for later hand-off. All tables ultimately live in MySQL, so you’ll be writing efficient joins, sub-queries, and window functions directly against that database to create analysis-ready views. Performance matters; I want the queries optimized and commented so they can be reused by the in-house tech team. Once the data is shaped, the next step is to craft an interactive, executive-level dashboard in Pow...
